I finally finished hooking up my 6 volt batteries and in the process, decided to clean up all the "spagetti" wiring that WW has in the battery cabinet. In stead of having all those wire connectors wing nutted to the battery terminals, I used 2 large busses that are available at any electical supply store that sells to contractors and placed all my (+) and (-) wires directly to them.
I also put in a disconnect switch for emergency shut off or when I want to work on the 12 volt system. I housed it in an old hot tub exterior outlet box I had laying around in the garage.
The positive buss will have a cover over it too.
Yes......the battery box is "RubberMaid"
